Relate Halftones With Similar Color Tones

A "halftone" is the array of tiny dots that make up a newspaper photograph. Scanned and digitized images, similarly, are composed of an array of small "bit-mapped" dots. To manage the relationship between a halftone image and the colors in other design elements, color may be added to these arrays with a wash between the dots. More subtle relationships can be achieved when the halftone is overlaid with one or more colored "duotones" — arrays of colored dots that (at least partially) reproduce and enhance the halftone image. Using duotone overlays, one hue can be made to subtly dominate an image. This may be used to suggest less obvious relationships among various elements.
